Description
Technical field
The present invention relates to machine-made sand concrete technical field, more particularly to a kind of lime stone Machine-made Sand and cobblestone Machine-made Sand
It is mixed with concrete.
Background technology
Ratio in general concrete shared by sand is generally 30%-40%, so sand is to concrete mix and hardening
Performance all has a major impact afterwards.(1) Machine-made Sand is generally Mechanical Crushing and formed, the more water caltrops in its surface, surface more coarse than natural sand
Long-pending big, accumulation voidage is high, needs increase water consumption and the material that is gelled in the case where configuring identical workability concrete compared to natural sand sand
Expect dosage.The Machine-made Sand particle that different process is produced also has larger difference, it is generally recognized that surface is rounder and more smooth, gill shape is few
Particle, the concrete performance of configuration is better, or reaches under identical service behaviour the slurry parcel, it is necessary to less, can reduce
Water consumption and gel material content.But found in long-term trial mix, under same water-cement ratio and equal workability, more water caltrops
Grain accumulation voidage height increases the contact area of Machine-made Sand and slurry so as to more be securely bonded to together, so more water caltrops
Coarse particle is all improved to the compression strength and rupture strength of concrete, while also increases the permeability of concrete.(2)
For influence for concrete work property, the influence of the no grading of influence and grain shape of sand surface texture is obvious, but
If matched somebody with somebody in same stages with same grain shape, surface texture can also influence the accumulation voidage of particle, equally influence coagulation
Dosage is just expected in native water requirement and gelling.Compared to the particle with smooth texture, the concavo-convex particle of texture becomes hour, accumulation in particle diameter
Voidage is bigger, and concrete can be made to become dry thick service behaviour under equal conditions and be deteriorated, but if in equal water-cement ratio, and ensure
Concrete has good service behaviour, and surface texture is thicker can also to improve bonding more firm between particle and slurry, from
And be advantageous to improve concrete anti-compression and rupture strength.But although the favourable slurry of sand rough and sand caking ability carry
Height, but coarse surface also increases the voidage on surface simultaneously, will also cause the increase of water absorption rate, after the concrete is cured
Moisture evaporation between particle surface and slurry, the increase of inside concrete porosity cause impervious reduction, may cause concrete
Intensity reduces with durability.(3) Machine-made Sand particle level pairing concrete mix service behaviour and hardening after intensity and
Durability also plays very important effect.Concrete is the accumulation body of a mixing material in itself, the shape after hydration and hardening
The building compound material that can bear the performance such as resistance to compression, tension, impervious into one.Natural sand incorporation concrete is replaced in Machine-made Sand
In, the slurry that one side Machine-made Sand forms lubrication with binder materials in early stage carrys out the mobility that package aggregate supports concrete, after
Phase hardens into Behavior of Hardened Cement Paste, the space on the other hand come between filler aggregate.If grain composition continuous phase answers bulk density bigger, institute
The slurry that need to be filled is fewer, can not only can also improve the impervious of concrete in the later stage that can obtain preferable mobility in early stage
Performance and durability, it is discontinuous or compactness declines if having disconnected grade if grading so as to reduce the contraction of concrete and creep,
It is unfavorable for later strength and concrete durability.
